Semiconductor apparatus with crosstalk noise reduction circuit

摘要

In order to reduce crosstalk caused between control signal wires in a semiconductor apparatus without increasing the size of the semiconductor apparatus, a noise guard circuit is provided at the opposite end of the control signal wire to the driver circuit. The noise guard circuit controls in such a way as to increase the impedance between the relevant control signal wire and a fixed potential when the logic of the relevant control signal wire is positive logic for driving the element, and as to decrease the impedance between the relevant control signal wire and a fixed potential when the logic of the relevant control signal wire is negative logic for driving the element.
